Anaerobic Membrane Bioreactors To Treat Municipal Wastewater At Ambient Temperatures, Matthew D. Seib Oct 2015

Anaerobic Membrane Bioreactors To Treat Municipal Wastewater At Ambient Temperatures, Matthew D. Seib

Dissertations (1934 -)

Anaerobic biotechnology is viewed as a sustainable alternative to aerobic biotechnology for municipal wastewater recovery. However, anaerobic processes have not been successful in cold climates. Past examples have not been able to meet low organic effluent concentrations, or have failed due to biomass washout resulting from low temperature operation and short hydraulic residence time. Recently, the anaerobic membrane bioreactor (AnMBR) has been shown to achieve low effluent organic concentrations and maintain stable anaerobic biomass. However, shortcomings have included high energy demands for membrane operation and poor understanding of microbial community structures within AnMBRs. This dissertation describes efforts to improve AnMBRs …

Insomniac Of The Soil: A Collection Of Poetry And Essays, Sarah E. Golibart May 2015

Insomniac Of The Soil: A Collection Of Poetry And Essays, Sarah E. Golibart

Senior Honors Projects, 2010-2019

“Insomniac of the Soil” is a homage to a landscape that has deeply informed Sarah Golibart's life and her artistic voice – the tidewater flatlands of Virginia’s Chesapeake Bay peninsula where her family lives and where Golibart has worked on farms since high school. Both her poems and essays are earthy, imagistic, and grounded – quite literally – in the soil as well as in a sensibility of ecological ethics and sustainability. “Insomniac of the Soil” is also a love song to the fervent and fallow cycles of the soil.

Morality Of A Carbon Tax: Transition To A Sustainable Economy, Timothy Lamendola Apr 2015

Morality Of A Carbon Tax: Transition To A Sustainable Economy, Timothy Lamendola

Binghamton University Undergraduate Journal

A carbon tax is needed to address the negative externalities caused by carbon emissions. Increased carbon dioxide concentrations in the atmosphere have a direct and negative impact on net social benefit to current and future generations. Our current human population has a moral obligation to future generations and, therefore, is responsible for excess burning of fossil fuels. This essential carbon tax is needed to help wean humans off their fossil fuel reliance. One should not be concerned with the economic losses this could cause because an economy based off unlimited growth is unsustainable and must be altered. A new, sustainable …

Linking Sustainability To Quality Management And Firm Performance, Rajat Mishra, Randy Napier Jan 2015

Linking Sustainability To Quality Management And Firm Performance, Rajat Mishra, Randy Napier

Faculty Publications

Environmental management practices have evolved significantly over the past two decades. During that time, sustainable operations management practices have purportedly made positive contributions to overall firm performance. This paper develops two conceptual frameworks regarding the relationships among specific elements of environmental management, quality management, and firm performance. We suggest that innovation in quality management mediates the relationship between design for environment and firm performance, and that statistical process control techniques moderate the relationship between environmental management systems and firm performance. We identify future research possibilities, based on these frameworks, to inform scholarly research and practice in environmental management and quality …

The framework defines key considerations for system design, steps for performance monitoring, and approaches for facilitating continual system improvements. It was developed by critically examining the …


Failure Of Science, Death Of Nature, H.F. Recher Jan 2015

Failure Of Science, Death Of Nature, H.F. Recher

Research outputs 2014 to 2021

As a people, Australians have lost contact with the world of nature, Risking the collapse of civilization. One factor in the alienation of nature in Australia is the failure of the scientific community to take responsibility for the technology created by the knowledge generated from scientific research. Science has failed to protect Australia's flora and fauna. Scientists must communicate more widely with society, but need to be educated on how to communicate and on their ethical responsibilities to others and other species. Government needs to show leadership in environmental management and nature conservation, while conservationists need to 'invert the paradigm', …

Impact Of Market Forces On Product Quality And Grassland Condition, David L. Michalk, Jianping Wu, Warwick B. Badgery, David R. Kemp

IGC Proceedings (1977-2023)

Meeting demands for livestock products which are predicted to more than double during the next 20 years, is central to the challenge of feeding the world sustainably. Smallholders will play a key role in achieving global security in animal protein. However, this requires a shift from subsistence to market-oriented farming where production efficiency not the number of livestock is the key focus with the aim of producing ‘more from less’. For grassland-based ruminant production, reducing stocking rate from current unsustainable levels under subsistence management is an essential first step to producing more production and profit from fewer animals. This is …


Mathematical Modeling For Platform-Based Product Configuration Considering Total Life-Cycle Sustainability, Tian Lan Jan 2015

Mathematical Modeling For Platform-Based Product Configuration Considering Total Life-Cycle Sustainability, Tian Lan

Theses and Dissertations--Mechanical and Aerospace Engineering

Many companies are using platform-based product designs to fulfill the requirements of customers while maintaining low cost. However, research that integrates sustainability into platform-based product design is still limited. Considering sustainability during platform-based design process is a challenge because the total life-cycle from pre-manufacturing, manufacturing and use to post-use stages as well as economic, environmental and societal performance in these stages must be considered. In this research, an approach for quantifying sustainability is introduced and a mathematical model is developed for identifying a more sustainable platform. Data from life-cycle assessment is used to quantify environmental factors; criteria from the Product …
